SPECIFICATION forming part of Letters Patent No. 783,437, dated July 14,1903. Application iled January I3, 1902. Serial No. 89,481. (No model.)

To all whom, t may concern,.-

Be it known that I, HERBERT MARSHALL STURGIS, a citizen of the UnitedStates, resid, ing at Kansas City, in the county of Jackson and State ofMissouri, have invented a certain new and useful Improvement in Heaters,

(Case No. 4,) of which the following is a full,

clear, concise, and exact description, reference being had to theaccompanying drawro ings, forming a part of this specification.

My invention relates to devices for heating curling-irons, and has forits object the provision of a structure of this class that may bequickly and effectively united with or placed upon a gas-jet and whichis also adapted for quick removal from the gas-jet.

- In practicing myinvention I employ a union adapted for quickengagement with and separation from the gas-jet, which union ispreferably screwed or otherwise integrallysecured to a duct formed,preferably, in the shape of a gooseneck, which duct projects for asuitable distance parallel to the union and is deiiected at right anglesthereto a sufficient distance below the union to clear the globe andglobe-holder and other parts of the gas-fixture, whereby existinggas-fixtures need not be modified nor globes that may be in placeremoved in order to effect the placement of the heater. The lowerangularly-extending portion of the duct is provided with a series ofapertures through which gas passed from the gas-jet through the unionand duct may issue. These apertures are arranged to produce flames lyingin a plane coincident with the vertical diameter of the said angular eX-tension to strike the bottom of a receivingtube located above theapertures. This receiving-tube is provided with end plates, 4: which arepreferably rigidly secured thereto.

The angular extension engagesthe lower portions of these end plates,loosely passing through a hole provided in one end plate and beingsecured to the other end plate by means of a machine-screw passingthrough a corresponding hole and having threaded engagement with theinterior of the duct to thereby prevent the escape of gas at the otherend of the duct, as well as to engage the same with `jet inciosed by aglobe.

the end plate. A bracing means is interposed 5o between one of the endplates and the vertical portion of the duct to prevent the ver'- ticaland horizontal branches of the duct from being displaced or sagging. Thetube having a gooseneck is preferably separably secured to theburner-tube, so that it may be replaced by a similar tube having anadded attachment in the form of a fitting including a single jet for thepurpose of creating alight.- ing-flame and a valve whereby the applica-6o tion of gas to the heating and lighting burners may becontrolled,'the valve being preferably so constructed that it mayentirely shut oi the gas to both of these burners, limit the flow of gasto either burner, or permit it to flow to both burners simultaneously.This construction is of especial utility where the device is to be usedin a room that has but one gas-jet, so that the application of myimproved heater to this single gas-jet will not 1o prevent illuminationin the room.

I have thus specifically outlined the preferred embodiment of theinvention; bntI do not Wish to be limited to this species of theinvention in all the claims.

I will explain my invention more fully by reference to the accompanyingdrawings, illustrating the preferred embodiment thereof, in which VFigure 1 is a side elevation of myimproved 8o apparatus,includingagooseneck, Without the lighting-burner attachment, theapparatus being shown in place upon an ordinary gas- Fig. 2 is a View ofthe apparatus of myinvention having a gooseneck with a lightingattachment added thereto substituted in place ofthe form of gooseneckshown in Fig. l, the apparatus being applied to a burner Without aglobe. Fig. 3 is a View similar to Fig. 2, illustrating the 9olighting-flame that may be secured by means of the tting supplied to agooseneck. Fig.

4 is a plan view of the heater. Fig. 5 is a sectional elevation of theapparatus of my. invention when modified as illustrated in Figs. 2 and3. Fig. 6 is a side elevation of the fitting added to the gooseneck,parts thereof being separated. to show their construction. Fig. 7isaview of the iittingillustrated in detail in Figs. 5 and 6, showingdifferent adjustments of the valve. Fig; Sillustrates the utility of thepreferred embodiment of the heating apparatus in holding a curlingironin place without subjecting the same to the heating-burner.

Like parts are indicated by similar characters of reference throughoutthe different figuros.

In the drawings I have illustrated one of the many well-known types ofgas-jets to which and from which my device can be readily attached anddetached. In thisinstance the gas-jet o is provided upon the end of agas-pipe b in the form of a wall-bracket having a controlling-cock clocated near the wall. The location of the valve or cock c isimmaterial, as the device of my invention is adapted for use inconnection with all forms of gasixtures now upon the market.

I employaduct d, made of thin metal. This duct is provided with a curvedportion e, that is preferably rigidly united with a union f by beingscrewed thereto. This union is adapted for Unthreaded engagement withthe gas-tip. This union is provided with a cap g, having a cylindricalextension 7L, around which is placed a section of rubber tube i, whichis clamped between the extension and the outer wall of the union,whereby the rub-- ber tube may be readily placed in engagement with theselected gas-tip and readily removed from engagement with the gas-tip,while at the same time a gas-tight fit is provided for conveying the gasfrom the pipe b through the duct d. This duct has a horizontal extension7c, which is joined with the portion e by the vertical or uprightstretch of the duct. The horizontal extension 7c is provided with a`series of apertures Z, constitutingjet-openings. I prefer to employthese distinct jet-openings rather than an elongated slot; but I do notwish to be limited to the jet-openings, which, in fact, I hereinconsider as the equivalent of a continuous slot, and the claims aredrawn with this equivalency in view; nor do I wish to be limited to theplacement of the jet-openings in a single straight line.

The receivingtube m, within which the tongs of the curling-iron n may beinserted, is rigidly secured at its ends to the end plates o and p, thistube constituting the preferred form of curling-iron support. The endplate o is provided with an aperture through which the duct portion lafreely slips, while the end plate p is provided with an aperture throughwhich a fastening-screw q may pass into engagement with threads providedwithin the bore of the duct portion k, the screw q being preferably inthe form of a machine-screw whose head is of a considerably-largerdiameter than the diameter of the duet, whereby the end platep is heldbetween the head and the end of the duct to not only secure theheatingtube min proper relation to the duct portion L,

but also to seal the end of the said duct portion to prevent the escapeof gas. To secure effective combustion of the gas passing through theduct, I provide an aperture. r, aording direct communication between thesurrounding atmosphere and the bore of the duct. By locating thisaperture, which is preferably in the form of a wide slot, in the bottomof the duct the escape of gas therethrough is prevented,while the air isreadily drawn within the duct or tube during the combustion of the gasto effect a thorough inter-mixture of the gas and air to produce a mosteffective combustion. A plug fr may be provided at the rear of the cutor slot r, which plug contains a very small opening r2 for the passageof gas, so that the gas may be forced past the opening r. As this cut orslot fr is likely to weaken the tube, which is preferably of a uniformdiameter throughout, I provide a bracing device which properlystrengthens the tube to prevent the weight of the curlingiron frombending the tube at the said slot. For this purposefan apertured plates, that is rigidly secured to and preferably stamped out of the sainemetal with the end plate o, is provided. The receiving-recess of thisplate engages the vertical length or stretch of the gas-duct d tothereby preserve the proper angular relation between thevertical andhorizontal lengths of the said duct, so that the presence of the sloto', which is preferably located in the horizontal portion 7c, does notdetract from the rigidity of the structure.

The heating-tube m coacts with the duct portion 7c to hold thecurling-iron in position; otherwise the curling-iron, although grippinga plate, would of its own weight tend to rotate to a vertical position.By interposing the curling-iron between the duct m. and the duct portionk the curling-iron is placed at a convenient angle to be readilyaccessible to the user.

The ducts d indicated in Figs. 2, 3, and 5 are adapted for substitutionin place of the duct d indicated in Fig. l. the vertical portion of theducts CZ of both forms is preferably separably connected with thehorizontal stretches 7c, for which purpose the contiguous ends of thevertical and horizontal portions of each duct are preferably threaded tohave threaded engagement with an elbow-fitting t, which may permanentlybe engaged with the portion 71:, it only being necessary to unscrew theVertical portion of the duct when it is to be replaced. The ductillustrated in Fig-f5.2, 3 and most clearly in Fig. 5 is provided withan elbow-fitting u, which at one end is adapted for communication withthe union or coupling f and at its middle portion for threadedengagement with the curved portion e. This elbow preferably constitutesa three-way cock, one passageway affording communication with the unionor coupling f, another passage-way with the duct d, and a thirdpassage-way with the lighting-burners. There is located in this ICO Forthis purpose fitting a valve u, adapted for four operative positions. Inthe position illustrated in Fig. 5 neither the heating-burner 7c nor thelight.- ing-burner t receives gas. In the left-hand illustration in Fig.'7only the lighting-burner "u receives gas. In the middle illustrationin Fig. 7 only the heating-burner receives gas. In the right-handillustration of Fig. 7 both the heating and the lighting burners receivegas. Thus the heating-burner may be used without preventing illuminationwhen there is but one gas-jet in a room.

The elbow-iittingu,as indicated, preferably has threaded engagement withthe curved portion e and the union f, being thus preferably interposedbetween the union and the duct. In substituting one form of duct foranother the union f is unscrewed from the one and screwed to the other.

By means of my invention only one eXtra part need be provided,as theonlyinterchangeable parts are the vertical portion of the duct (l withthe curved portion e (shown in Fig. l) and the vertical portion of theduct cl with the fitting or cock u, (illustrated in Fig. 5,) the balanceof the apparatus being common to both of these interchangeable portions.

It will be readily seen how the form of fitting illustrated in Fig. 3maybe transformed into the style of tting illustrated in Fig. 2, whichmay be accomplished by substitutingl the portion d of one structure forthe portion d of the other.

It is frequently desirable to place the fixture on a table or othersupport when not in use and have it stand upright. The plates 0 and pare continued below the tube portion 7c to afford a suitable standardfor the appliance. In order to prevent the weight of the union orcouplingf and the added illu minating-tip from overbalancing thestructure, I provide a knob w at the bottom of the elbow t, the lowersurface of the knob coinciding with the lower edges of the said plates,there being thus three supports placed in alinement to constitute a basefor the apparatus.

It will be observed that I have provided a union with a smooth orunthreaded bore, whereby the union may be readily placed in engagementwith a gas-tip by a mere vertical motion and removed from thisengagement also by a mere Vertical motion. Thus the curling-iron heaterneed not be permanently associated with any given gas-jet, nor need anygas-jet be especially readjusted or modified to suit the heater.Heretofore curling-iron heaters in commercial use have been providedwith threaded unions adapted for threaded engagement withspecially-provided gas-jet fittings, which necessitated a perfect andcomplete engagement between the unions and the special fittings, so thatthe position of the curling-iron heater with reference te the wall couldnot be readilyadjusted. By means of my invention the curling-'ironheater may be placed in any position and have its position readilyreadjusted without causing a leakage of the gas.

While I have herein shown and particularly described the preferredembodiment of my invention, it is obvious that changes may be madewithout departing from the spirit thereof, and I do not, therefore, wishto beV limited to the precise consti-notion shown; but,

Having thus described my invention, I claim as new and desire to secureby Letters Patentl.
